The Scala Bio Fir Anti-Cellulite lingerie is available in stores (you can look online, but as this post is being written, all styles are out of stock). John Lewis feels confident in the line -- it did its own research, letting 50 women wear the underwear six hours a day for 30 days, finding an 80 percent success rate. The store's lingerie buyer, Helen Spencer, said,

"We are approached very regularly with products promising the kind of results women want, but which haven't stood up to scrutiny. This is where Scala's range is different -- it does exactly what it says on the tin."

She went on to explain that, because the technology is within the fabric, "the anti-cellulite properties remain intact for the lifetime of the garment, withstanding countless washes."

Okay, so they've been tested, shown to work, and they remain effective for a long, long time. What's the catch? It's not the price -- these wonder-undies are only £25 or £30 (between around $37 and $45), depending on the style you select. However, there are no shops in the States, so if you have to make a trip to England or Scotland to buy them, we suppose that price becomes less of a bargain.

Still, given the chance, we'd definitely give these a try. How about you? In the meantime, we'll settle for the shapewear shown below.

Somewhere someone is patting herself on the back for coming up with such a clever name. But cuteness aside, this is a seriously sleek shapewear. The all-in-one nylon/elastane briefer banishes back fat and minimizes your mid-section while shaping and supporting your breasts with hidden underwire cups. Wear it under just about anything for immediate smoothing. It's like a tummy tuck, without the gross surgery.$85.00www.wacoal-america.comSHOP MORE SHAPEWEAR
